The aim of this study was to microbiologically asses some raw materials (maize and wheat) from a representative feed mill in Romania, in two consecutive years, both for the raw materials received and for those in the unit's stock; the microbiological contaminants that were analyzed were yeasts and molds. Regarding the maize samples taken upon receipt in first year, it was found that 90.9% had positive results, with an average value of 2600.8 cfu/g; in second year the proportion of positive samples was 84.3%, with an average value of 2132.5 cfu/g. Of the total wheat samples taken in first year upon reception, 89.1% were positive, with an average value of 2554.8 cfu/g; in second year the proportion of positive samples increased, reaching 93.3%, with an average value of 2171.4 cfu/g. The application of all measures capable of preventing contamination prevented the contaminated batches from entering the production process, while avoiding the possibility of contamination of other batches of raw materials and finished products (compound feed).
